Our DNA is what makes us so different from other people. Everyone has a unique set of genetic material which can help in identification. In DNA there is the section of epigenetics. This is the study of changes in gene activity that is not brought about by the change in the gene sequence. The article below elaborates on genes.
It is always advisable to avoid inbreeding in both plants and animals. In most cultures, human beings are not allowed to marry their relatives. The result usually is children having defective characteristics like slow development. However, if relatives have intermarried so many times, and the child is married to a person in a similar situation, the child may be superior for example in physical fitness.
There is a condition in which organism mutate and form a completely new strand of DNA. It is known as Mosaicism. For example, an embryo may mutate when it only has 8-16 cells. In twins, the two embryos may interact with each other before separating and coming up with completely new DNA strands. Such an organism has patches of different DNA and is known as a chimera.
Proteins are coded in 3 base layers in DNA. After copying of the DNA, there is the mechanism of proof-reading that confirms the copy is the same as the original. Mistakes can be made in the proof reading although they are rare. For example, in Haringtons disease, there is the duplication of CAG. As the mistakes accumulate with each generation, the disease is worse from parent to child.
Many are times when a virus invades the body; it goes on to the cell. When it is integrated, a mutation may occur thus deactivating the virus. The virus, however, remains in the genome and replicates every time the cell is copied. If it is copied into a sperm or ovum cell, then the cells of the embryo will all have the virus thus building an incorporated virus over tome.
There is the case of jumping genes. These are the king of genes that can detach themselves from a DNA strand and later on reattach themselves. These do not have many effects, and the effects are dominant in maize seeds. Many are times you may have seen that maize grains have a lot of different colors. These are a perfect example of jumping genes.
The DNA of all of the living organism is usually formed on four base strands. This may lead to you thinking that the only four DNA to exist is through this four base strands. This was however proved wrong where there were surviving cells with completely different DNA structures. This means that all living things have a common ancestor who decides the base structure of their DNA.
An individual gets their chromosomes from both parents. Mitochondria, however, they get from only the mother. If the cells have mutated, it may pose a big problem. This can be solved by transferring the nucleus from a fertilized egg to one that is not fertilized.
